Louisville voters reject extension of historic preservation sales tax for 2029–2038 (unofficial 2026 results)

In a result that will reshape how this Boulder County city pays for its own history, Louisville voters on Tuesday rejected a ballot measure to continue the city’s 0.125% historic preservation sales tax, with unofficial returns showing 53.21% voting against — 5,036 votes — and 46.79% in favor, 4,428 votes, according to Louisville city officials. The margin of roughly 608 votes means the tax, first approved by voters in 2008 and extended in 2017, will expire on December 31, 2028, and the share of its revenue dedicated to the Louisville Historical Museum campus will stay at 20% rather than rising to 30%.

The defeat marks only the third time Louisville has asked voters to sustain the tax, and the first time they have said no, Colorado Hometown Weekly reported. What makes the rejection striking is what it leaves in place: the tax itself keeps running through the end of 2028, but the city will have no voter-approved mechanism to renew it, and no expansion of its permitted uses. For residents, the practical effect begins in 2029, when the funding stream simply stops.

A Tax Built Over Two Decades, Now Heading for Expiration

The measure on Tuesday’s ballot, Louisville’s Ballot Issue 2B, asked voters to authorize a continuation of the 0.125% sales tax beginning January 1, 2029, and running through December 31, 2038, generating an estimated $1.5 million in its first year. The proposal would also have broadened what the money could fund — allowing spending on city programs and capital projects that promote the city’s history and cultural heritage — and would have increased the museum campus allocation from 20% to 30% of annual revenue. None of that takes effect. Colorado Hometown Weekly reported that revenue from the tax flows into the Historic Preservation Fund, established when voters first approved it in 2008, and that the 2017 extension added the 20% museum dedication.

The question was structured as a voter-approved revenue change under Article X, Section 20 of the Colorado Constitution, the state’s Taxpayer’s Bill of Rights provision that normally limits how much revenue local governments can collect and spend. By failing, the measure means those constitutional limits apply without the exception the city sought.

Six Other Charter Measures Split the Rest of the Ballot

The historic preservation tax was one of seven measures Louisville voters weighed, and the rest of the ballot split in both directions. As of Wednesday morning, Colorado Hometown Weekly reported that voters were supporting four of the six proposed amendments to the city’s Home Rule Charter while rejecting two.

Ballot Issue 2D, changing when elected officials take office to after election certification rather than at the first council meeting following the vote, won 75.2% support. Ballot Issue 2F, allowing public bodies to meet in “other accessible venues” beyond public buildings and facilities — a change city staff said would permit joint meetings in neighboring municipalities — passed 55.3% to 44.7%. Ballot Issue 2G, requiring resident petitioners to meet with the city manager and staff for public review and comment before submitting an initiative or referendum, passed 54.4% to 45.6%.

What the Numbers Mean for City Hall

Voters embraced measures that made government more accessible and accountable — later seating of officials after certification, more flexible meeting locations, and a public review step for citizen petitions — while rejecting measures that would have narrowed public participation or expanded closed-door sessions. The historic preservation defeat sits in that same pattern: residents declined to lock in a new decade of tax revenue, even for a purpose voters had endorsed twice before.

For the Louisville Historical Museum campus, the outcome is concrete. The 20% allocation approved in 2017 remains the ceiling, and with the tax expiring December 31, 2028, the museum and the broader preservation fund face a hard sunset. City officials have not yet said what preservation spending looks like after that date; what is certain is that the question voters answered Tuesday will not be put to them again in this form, since the measure failed.

The unofficial results become effective November 25, 2026, and the final certified tally will determine the official record — but the tax continuation is failing.
